White Valentine's Day is the date of February 14th, which is the western Valentine's Day. In Japan, it has been a long-standing custom for women to give men chocolates on Western Valentine's Day. It is also customary for female employees to give chocolates to their bosses at work. However, these chocolates, which do not imply love, are called "Eri chocolates" in Japan. The person who receives "Eri chocolates" must return the favor. Since the gift is usually given to your boss, on March 14th, you will receive a gift from your boss that is two or three times more expensive than the Eri chocolates you originally gave to your boss. For example, if you send 200 yen worth of chocolates, you will receive a 1,000 yen handkerchief in return. That's why on February 14th, there are some people who try to give Eri chocolates as the first gift for the purpose of recycling. It doesn't mean much. It's a gift from a woman to a man. In the white Valentine's Day.
